Should this be my next chapter or should I write a few more first?

I'm writing a story on Wattpad and I'm not sure if I should post a particular chapter here.

Please read the last 2-3 chapters (or skim them; the main thing is that you know the general content) and then tell me what would be better.

The chapter in question is this:

After dinner, Kia went to the common room, but I preferred to go to our room. There I saw that I'd missed a call from Mum while I was with Chiara.

Of course, I called her back immediately.

"Hi Mum," I greeted her cheerfully after she answered the call. "Is Dad here too?" I asked immediately, because I was desperate to tell him and Mum everything.

"Hello Lia," she greeted back, just as cheerful. "No, unfortunately not. He and Milo are at Grandma Juliane's hospital. She doesn't seem to be feeling well at all. That's why I called you. I'm at her apartment right now to pick up a few things for her."

Grandma Juliane, Dad's mother, had to go to the hospital! That didn't sound good at all. Especially considering she was already 87 years old. Concerned, I asked, "What happened?"

"I don't know either. We visited her this afternoon and had lunch with her. We talked, and she asked about you. Anyway, after a while, she felt dizzy and developed a severe headache. I helped her get into bed and lie down while your father called an ambulance. They took her away immediately. She was examined at the hospital. She had obviously had a stroke. Thanks to the doctors, she's feeling a little better, but Juliane has to stay in the hospital for a while longer. She's receiving medication and will undergo surgery. The doctors, however, don't seem to have much hope for her recovery," my mother said.

I listened in silence, tears streaming down my cheeks and I sank to the floor. Even when Mum was finished, I didn't say a word. I didn't want to lose Grandma Juliane!

"Lia?" Mum asked after a while. "Are you still there?"

"Yes," I said, my voice shaky. That was all I could say. Then I hung up and tried to call Dad, who was with Grandma Juliane at the hospital. I wanted to ask him to give her the phone. But Dad didn't answer.

I tried a few more times, but eventually gave up. Dad was probably too worried about Grandma Juliane to pay attention to his phone.

Later, Katharina, Chiara, and my cousins ​​tried to call me, but I didn't answer. There was only one person I wanted to speak to: Grandma Juliane.
